DOOR-SECURER.

Specification of Letters Patent.

Patented Sept. 6, 1910.

Application filed September 21, 1909. Serial No. 518,790.

. Sonoma and State of California, have invented a new and Improved Door- Securer, of which the following is a full, clear, and exact description.

My invention relates to a class of attachments for doors, which may be readily applied and removed, and which will prevent an improper opening of the door.

The purpose of my invention is to provide a door securer of novel construction, which is light, small, convenient in its application, will securely retain doors in closed condition, may be readily applied to doors whether flush with their casements or depressed therein, and that may be rapidly produced at a low cost.

The invention consists in the novel construction and combination of parts, as is hereinafter described and dened in the appended claims.

Reference is to be had to the accompanying drawings forming a part of this specilication, in which similar characters of reference indicate corresponding parts in all the views.

Figure l isa plan view of the improved door securer, and a transverse sectional view of a portion of a door easement whereon the securer is applied; Fig. 2 is a transverse sectional view of a portion of a doorand its easement, and a longitudinal sectional plan view of the improved door securer applied for securing the door in closed condition on the Casement; and Fig. 3 is a side view of a door easement in part, and a like view of the device connected with the Casement.

The improved door securer presently described is adapted for general use, on doors having mortise locks, or such as are secured upon a door exteriorly and project beyond the easement, the device being also available for releasably securing a door closed in its easement when moldings on the latter project beyond the surface of the door on the side toward which the door swings.

The improvement comprises the following details:

5 indicates a rack bar formed of a flat metal strip of proper thickness to insure rigidity, and having parallel side edges. y A transversely central slot a of proper width is formed longitudinally in the bar 5, and terminates a proper distance from each end thereof. Upon one end of the bar 5 a hook member or lateral extension 6 is integrally formed or secured thereon, said hook member or flange being bent laterally at a right angle to the body of the slotted bar. The side edges of the slot a are parallel with the exterior side edges of the bar and with each other, and in each of said edges that define the slot a, rack teeth b are formed which extend in series from the end of the slot nearest to the hook 6, a distance about equal to half the length of the slot.

A preferably rectangular box frame is provided, having two side walls 7, 7, which are spaced apart in parallel planes, a distance which permits the frame to be slidably mounted upon the rack bar 5, and loosely embrace the sides and edges thereof. In the side walls 7 of the frame, two rectangular openings c are op-positely formed, leaving the end Walls remain intact with other portions of said side walls, and on each end wall an integral cylindric journal box cl is formed, the bores in which are axially alined. An adjusting screw block 8 is employed, having a cylindrical body, and' a journal 8s, formed on each end thereof, said journals having loose engagement with the boxes d respectively. On the peripheral wall of the block 8, a coarse screw thread c is formed, which is of a pitch that will adapt said thread to freely engage with the nearly opposite teeth Z2, such an engagement being effected by sliding the box frame toward and over the teeth until the screw block has Contact with the adjacent teeth between which the end of the thread c will enter if the screw block is rotated in a proper direction. Upon one side wall 7 of the box frame at the end that is nearest to the hook flange 6, an abutment fiange 9 is formed, which projects outward at a right angle from said side wall.

At the outer end f of the abutment flange 9, one end of a presser plate l0 is hinged thereon, as shown in Figs. l and 2, thus adapting the flat body of said plate to lie flat upon the abutment flange when the presser plate is folded thereon, the width of the latter being such that it will freely pass through the slot a between the ends of the rack teeth as is` indicated in Fig. 2. On the outer end of the abutment flange 9, in-

tegral with said flange a prop brace 9EL is formed, which is inclined downward and toward a shoulder g that is an end wall of an adjacent journal box CZ, the brace seating on said shoulder, and supporting the hinge joint f, together with the flange 9, and presser plate 10, when the latter is adjusted as shown in Figs. l and 2.

In the drawings, the improved door securer is shown as applied for holding a door A on its easement B, said door having a lock C embedded in a mortise therein. In this example of the application of the improvement, the door and easement are represented as level with each other on the side that receives the device. In the Casement as usual, a strike plate D is secured in a recess formed in the amb of the easement B, said strike plate having an opening it formed in the edge portion at the jamb of the easement. The lock C, as usual, is provided with a latch bolt E, which is manipulated by a spindle and knobs thereon in the ordinary manner, these parts being omitted from the drawings, said latch bolt in service passing into the opening t.

In applying the improved securing device, the hook liange 6 while the door is open, is introduced into the opening z, and socket h, the body of the rack bar 5 thus being disposed in contact with the strike plate D, and as there is generally a crevice between the door and easement, there will be sufficient space therebetween for the rack bar to lie between said parts, as shown in Fig. 2.

To facilitate the closure of the door, the box frame and parts mounted thereon, are moved toward and near to the outer end of the rack bar 5, as shown in Fig. l, the door is now closed and the latch bolt E may be retracted as shown in Fig. 2. The box frame is now moved toward the door and the screw block 8 is manipulated so as to advance the presser plate 10, until the latter is pressed irmly into contact with the door and casement, as is shown in Fig. 2.

It will be seen, that the improved door securer will, when applied as shown, positively hold the door in closed condition, and that said device cannot be displaced until the box frame is purposely retracted to the position shown in Fig. 1, which may obviously be effected by a turning movement of the screw block 8, in a proper direction.

If molding on the door easement projects outside of the door, so as to present an oifset shoulder at the crevice between the door and easement, the presser plate 10 is altered in adjustment by folding it into the position shown by dotted lines in Fig. 2, which will adapt the abutment flange 9, alone to bear upon the surface of the door, when the screw block 8 is adjusted for such a purpose.

It will be evident, that the device will effectively secure a thin or thick door in closed adjustment, as it may be readily adjusted to compensate for different thicknesses of doors or changes in position had by an opening 7i., in a strike plate D.

Having thus described my invention, I claim a new and desire to secure by Letters Patent :HM

l. A door securer, comprising a flat bodied rack bar, a hook bent laterally at an angle on one end of the rack bar, said bar having a longitudinal slot therein and teeth on an edge of said slot, a box frame slidable on the rack bar, an abutment flange projected laterally at one end of the box frame, and a screw block rotatable in an opening in the box frame, said screw block being adapted for engaging with the teeth in the rack bar.

4. A door securer comprising a rack bar having at one end an angular portion, said bar having a longitudinal slot, the edges of which are provided with teeth, a frame slidable on the rack bar, a screw block rotatable in the frame for engaging the rack teeth, and an abutment flange extending laterally from the end of the frame adjacent to the angular portion of the bar.
